Frequently asked questions about the Internal boarding category
What is Internal boarding and what is it used for?
Internal boarding is profiled wooden cladding for interior walls and ceilings, typically made from spruce or pine with common sizes like 12x95x5100, 12x120x3600, 14x121x2700, used to finish living rooms, hallways and utility spaces.
What wood species are available for internal boarding?
Main options are spruce and pine; products come in STV profiles (12x95, 12x120) and lacquered OPUS variants such as white lacquer 14x121x2700.
What are standard sizes for internal boarding and how to choose?
Common sizes include 12x95x5100, 12x120x3600, 12x120x5100, 12x95x2700, 14x121x2700. Choose width and length by wall area and joint frequency — 12x120 works well for larger surfaces, 12x95 for narrow spaces.
What is the difference between OPUS and STV profiles?
OPUS profiles are typically wider (e.g. 14x121) and come with a white lacquered finish; STV is a standard profile in 12x95 or 12x120 sizes intended for natural look or further surface treatment.
Can 12x95 and 12x120 boards be used on ceilings?
Yes — both sizes are suitable for ceiling cladding. 12x95 is easier for narrow or complex areas, while 12x120 covers large surfaces more quickly.
Do boards need pre-treatment before installation?
Check moisture content and allow acclimatisation if needed. OPUS lacquered boards are generally installation-ready; STV panels can be treated with preservative or finished with lacquer as required.
What fixing spacing is recommended for boarding?
Fixing depends on profile and substrate: 30–50 cm between battens is common and provides secure fastening; for long boards use closer or continuous battens for support.
Can OPUS and STV boards be painted or lacquered after installation?
Yes — STV panels are commonly painted or lacquered post-installation for protection and appearance. OPUS white lacquered 14x121x2700 comes pre-finished, though additional coats can be applied.
Which boarding is better for wet rooms — STV or OPUS?
For wet rooms, lacquered or specially treated boards are preferable. OPUS white lacquer provides superior surface protection, while STV can be made suitable by applying preservative and lacquer.
How to calculate amount of boarding needed for a room?
Measure the total wall area and divide by the board usable width (e.g. 95 mm or 120 mm). Add 5–10% for cuts and waste, especially with openings and angled joins.
